Android, an open source mobile phone platform, improperly checks developer certificates when installing packages that request the shared user identifier (uid) permission.
Normally, Android applications will be allowed to share a uid if the packages are all signed by the same developer certificate and request permission to do so at install-time. This allows for packages from the same author to share data. Without enforcement of that behavior, it is possible for any application to be installed in such a manner that it gains access to another (existing) application's data.
